Specification of Letters Patent. Patented A 19 i921;

Application filed January 5, 1921. Serial No. 435,260.

To all whom it may concern Be it known that I, BERNARD P. SMITH, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Adjustable Drains and Traps for Refrigerators, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention consists in the novel construction and combination of parts hereinafter particularly described and distinctly claimed.

The object of my invention is to provide an improved adjustable, detachable and swinging drip-pan and drain-trap, for household and store refrigerators; which will be of low cost and highly efficient in operation; which may be quickly installed upon the usual fixed drain-pipe or sewer connection already in the building; which will effectually trap all sewer gas, and prevent the discharge of same into the room containing the refrigerator; and which may be quickly swung around after installation, to receive the drain-water from the drip-spout or drip-pipe of various forms of refrigera tors, no matter at what point beneath the refrigerator its drip-pipe may be located.

In the drawings,

Figure 1 is a vertical section of my improved drip-pan and drain-trap, applied to a household refrigerator sewer-connection, and

Fig. 2 is a front-elevation of the lower portion of a household refrigerator, with my drip-pan and drain-trap in position to catch the drain-water from the drip-pipe of the refrigerator.

The numeral 1 designates the horizontal arm of the drip-pan, the conical body 2 of which is provided with a tapered portion 3, which is mounted to revolve in an internally tapered bearing-nipple i; the lower end of the latter being threaded into the upper end of the usual sewer or drain connection 5 projecting above the floor 6 of the room in which the refrigerator 7 is located.

Formed around the interior of the said is filled with drip water during use and forms a very effective seal against the pas- '7 sage of sewer-gas into the room through the oint between said bearing-nipple i and the tapered journal portion 3, the lower end of the latter being submerged at all times .during use 111 the water contained in said trap, as shown in Fig. l.

Removably seated in the annular recess 9, at the upper end of said conical body 2 of the invention, is a common strainer-plate 10, which forms a bottom for the end of the pan which is opposite the said horizontal arm 1 thereof, but which can be readily taken out for cleaning or repairing the parts,

of the well-known form of trap 11 that prevents the entrance to the room of sewer gas directly through the discharge member 12.

Said trap 11 is the main trap of the drippan, and it is located beneath said strainerplate 10, on the interior of the said conical body 2. Its construction and function being well known, no further description thereof need be given, except to say that being mounted to rotate, its location, and the conical shape of its exterior, are new sofar as known to me.

It will be observed that a body ofdripwater is contained inthe said conical body 2, and rotates therewith whenever the said body is rotated, in changing the position of the drip-pan arm 1.

An adjustabledrip-pan for refrigerators,

composed of a horizontal-arm portion, a conical bodyto which one end of said arm is connected, a main gas-trap in said body, a strainer above said main gas-trap, a bearing-nipple to be connected to the drain-connection of the room, a U-shaped trap membar on theinterior of said nipple, and a ta- In testimeny whereof, I have signed my pered portion at the lower end of said coniname to this specification in the presence of cal body, projecting downwardly into the 1 two subscribing Witnesses.
